Potencial de espécies de Bambu como fonte energética

Abstract

The objective of this research work was to evaluate the characteristics of biomass and charcoal of Bambusa tuldoides, Bambusa vulgaris var. vittata and Dendrocalamus asper in order to investigate its potential for energy use. For comparative purposes, we used trees of Eucalyptus grandis x Eucalyptus urophylla hybrids trees with 6 years were employed. The biomass was characterized (specific gravity, proximate analysis, high heating value and energy density). The charcoal was produced with a heating rate of 1,67 °C.min-1 and final temperature of 450°C for later characterization (specific gravity, proximate analysis, high heating value, energy density and gravimetric yield). The bamboo species showed similar or superior energy characteristics in relation to the eucalyptus hybrid, except for the volatiles and ash content. The bamboo species has energy properties that indicate their potential for use as energy source.
